I can think of a lot of functions that rearrange data in MATLAB. I've long suspected that not all of these are well-known, though some are clearly daily tools. Maybe... 더 읽어보기 >>

In MATLAB, the simplest form of the function unique returns the unique values contained in a numeric vector, with the results sorted. This is often acceptable, but sometimes a... 더 읽어보기 >>

I've fielded some questions recently about how to coordinate multiple arrays changing simultaneously. One example is removing elements for two arrays in the case where either... 더 읽어보기 >>

The other day, one of my MathWorks buddies, Peter, asked me if I knew any tricks for vectorizing the notion of the colon (:) operator. For me, this sort of inquiry sometimes has an... 더 읽어보기 >>

In Sarah's blog, Dan asked about speed of removing elements. There are a number of ways of deleting elements in MATLAB. So, what's the "best" way? ... 더 읽어보기 >>

Using MATLAB, there are several ways to identify elements from an array for which you wish to perform some action. Depending on how you've chosen the elements, you may either... 더 읽어보기 >>

This post continues in the theme from my last post, where people routinely come to me on a topic. Today I want to distinguish
between indexed assignment, where you can take advantage of scalar... 더 읽어보기 >>

MATLAB has the concept of Not-a-Number, also known as NaN for quite some time. Following the IEEE 754 Standard for Binary Floating-Point Arithmetic, some floating point calculations result in NaN,... 더 읽어보기 >>

We can sometimes be motivated to reverse things in Boston. And I occasionally get asked how to reverse the sort direction from MATLAB. So instead of sorting A and then having B follow... 더 읽어보기 >>

I have had customers ask me occasionally about what happens during an indexed assignment when indices are repeated. The answer is that it depends on how you do the... 더 읽어보기 >>
